Polished Concrete

Applied Coatings has polished hundreds of thousands sq/ft of concrete over our history. Our factory trained craftsmen have the very best training as well the industry’s largest and most advanced polishing equipment and materials.

The general rule is to start the initial grinding with a coarse 16 or 30 grit diamond and finish with a 1500 or 3000 grit diamond, depending on the gloss level required.

These diamonds are impregnated inside a metal- or resin-bonded segment.

The use of 16 or 30 grit size diamonds, then use 60/80 grit diamonds followed by the 120 grit metal bond segments.

The polishing process begins with a 50-grit diamond resin pad instead of a metal segment.

When using the resin pads the steps may be 100 grit, then 200, 400, 800, 1500 and finally 3000 grit.

Throughout the process a densifier is used to harden the concrete surface, which allows the concrete to be polished.

A number of densifiers can be used; these consist of a lithium, potassium and sodium silicates.

The concrete is then sealed with a natural-look impregnating sealer; this sealer penetrates 2–5 mm inside the pores of the concrete preventing any deep staining from oils and spills.

A final polish with a high speed burnisher will complete the project and give the concrete a mirror like finish.
